良、恶性孤立性肺结节CT增强扫描强化程度的比较

Comparison of Degree of Contrast Echancement between Benign and Malignant Pulmonary Solitary Nodules during CT Scanning .

利用CT自动注射器造影增强及薄层CT扫描,作者对12例恶性孤立性肺结节和11例良性肺结节的CT增强扫描强化程度作了比较。初步结果表明,在静脉注射造影剂后1～2分钟内CT扫描,恶性孤立性肺结节的病灶中心CT值升高33.92±9.52(Hu),而良性孤立性肺结节的病灶中心CT值仅升高9.86±7.26(Hu),二者之间的差异较为显著(P<0.05)。作者认为CT增强扫描的强化程度有可能成为鉴别良、恶性孤立性肺结节的CT分析指标之一。

Using CT automatic injector contrast medium enhancement and thin-section CT scanning, the authors compared the degree of contrast medium enhancement of 12 cases of malignant pulmonary solitary nodules and 11 cases of benign pulmonary solitary nodules. The preliminary results showed that CT value increase was 33.92+9.52(Hu) incleasion center of malignant pulmonary solitary nodules, and the CT value increase was only 9.86+7.26(Hu) in lesion center of benign pulmonary solitary nodules, the difference was of significant (p<0. 05). Basing on the preliminary results of the experiment, the authors speculated that degree of contrastmedium enhancement would become one of the differential diagnosis indexes between the benign and malignant pulmonary solitary nodules.
